  • Patent number: 6591974
    Abstract: A spout is used for confining the grain flow from an auger. The auger may be a combine, grain cart unloading auger or a grain auger. The spout includes a chute that mounts on the auger tube. An overflow opening in the chute allows grain or other matter to flow out of the spout if the outlet of the chute is plugged. This prevents filling and overloading of the auger and consequent auger damage.

  • Patent number: 5447274
    Abstract: An irrigation apparatus for parks, golf courses, acreages, sports fields, school yards, etc., is mounted on a small trailer. It includes a sprayer head of the impulse type, a self-priming centrifugal pump for supplying water under pressure to the sprayer head and an engine for driving the pump. A hose carried by the trailer is connected to the pump inlet and may be used to supply water to the pump from a lake, stream or a water line. Where a pressurized water supply is available, the pump may be used to boost the pressure and provide improved coverage and a better misting action. If the existing pressure is high enough, it can be connected to a direct inlet to the sprayer.
